Research on the Dynamic Behaviors of Semi-Rigid CFST Frame-Shear Wall
Concrete filled steel tubular (CFST) structure is a new type of structure. Assuming that concrete filled steel stub frame-shear wall is continuous elastic structure with infinite degree of freedom, free vibration equation is built. Furthermore, the effects of semi-rigid connection on natural periods and frequencies are studied. The formula to calculate the coefficient of natural periods is deduced. ANSYS is employed to determine the modal analysis. The results obtained from finite element analysis are consistent well with those obtained from formula. The results show that semi-rigid connections tend to increase the natural period. However, the effect on higher modes is negligible. The seismic design suggestions of the semi-rigid concrete filled steel stub frame-shear wall are proposed. The proposed methods may supply references for the engineers.
